Let default constructor initialize the GUIMetadata type

[zsoerenm]

Something like this would be helpful e.g.

function Resistor(; name, R)
    @named oneport = OnePort()
    @unpack v, i = oneport
    pars = @parameters R = R
    eqs = [
        v ~ i * R,
    ]
    extend(ODESystem(eqs, t, [], pars; name = name, gui_metadata = GUIMetadata("Resistor")), oneport)
end

Maybe a symbol would fit better than a string?

[ChrisRackauckas]

This seems misguided. Will this just be the same as the type name that would then be used for better lowering. @YingboMa should we just add that first?

[YingboMa]

Should we always instantiate a component like

@component function Resistor(; name, R)
    @named oneport = OnePort()
    @unpack v, i = oneport
    pars = @parameters R = R
    eqs = [
        v ~ i * R,
    ]
    extend(ODESystem(eqs, t, [], pars; name = name), oneport)
end

?

[ChrisRackauckas]

I think so. And it would make a Val(:Resistor) type information or something?

[YingboMa]

We then have to assume all the components are instantiated in the same world age, but I guess it's a fair assumption.

And it would make a Val(:Resistor) type information or something?

Since it would be a very simple type system within MTK, we would use some other encoding that's independent from Julia's so that we don't take unnecessary compile time hit.

[ChrisRackauckas]

oh yes no val. But yeah, let's go this route.
